/* Pinch points.
 *
 * Rides on punctuality.css for the palette, page shell, cards, filters and
 * tables, and adds only what this page has that /punctuality does not: the
 * live board, the ranked link table, the hour profile chart and the formula.
 *
 * Two traps this file is written around, both previously paid for on this
 * site:
 *
 *   [hidden] is an author-level rule like any other, so `.map-holder {
 *   display: block }` silently beats it and the element stays on screen. The
 *   guard below settles it once for every element on the page rather than
 *   relying on each rule remembering.
 *
 *   A flex or grid child defaults to min-width:auto, which refuses to shrink
 *   below its content -- one wide table then pushes the whole page sideways
 *   on a phone rather than scrolling inside its own box. Every flex child
 *   holding wide content here carries min-width: 0.
